AuthorTopic: solving IR (Read 1428 times)

I have attached a slide here. It containd an IR spectra. I need to deduce the structure.I have done it in the following way:Broad 2571-3300 cm-1 for carboxylyc OH1717cm-1 for carboxylic COHence carboxylic functionality is confirmed.For the rest, 1265cm-1 is it suggesting CH2Br?I read that methylene protons ahow a characteristic absorption at about 1465cm-1So here the peak at 1432cm-1 may indicate methylene.Thus I am thinking that the structure may be BrCH2CH2CO2H, i.e. 3bromopropanoic acid.Am I correct?

C-O stretching generally occurs at 1320 - 1210 cm-1, at a medium intensity. Then which one here can be for C-O single bond? 1395 and 1432 cm-1 can they be assigned for C-O? because they are of medium intensity. 1265 is high, 1342 is low in intensity, so I think they are not for C-O.Then the preoblem is how to know the position of Br in the chain. Is it at the terminal C or at the alpha C? I cannot understand this.
